Transcripts
hello class this is our first video
lecture in our subject
highway and railroad engineering so i
have already given to you your module
number one
study guide for module number one so uh
we will just
briefly discuss the uh the
content of the references as mentioned
in this
um module so
highway and railroad engineering for the
first part
we are to discuss the importance of
transportation
so here it creates stopping natural
resources
and markets and maintaining a
competitive edge over other regions and
nations
are linked closely to the quality of the
transportation system
how so well the speed costs
and capacity of available transportation
have a significant impact on the
economic vitality of an
area and the availability to make
maximum use
of its natural resources
so we are to maximize our natural
resources we will be needing
to improve our transportation system
why so well um does it mean that
having a good transportation system is
an assurance in economic success of a
country
well the answer is well if
only the transportation itself it is not
an assurance
rather it has a
impact it has a significant impact for
the
economic growth as mentioned here in the
second paragraph it reads
good transportation in itself so it says
here
so good transportation itself will not
assure
success in the marketplace as the
availability of transportation
is necessary but insufficient condition
for economic growth
is
success for that certain city
so meron roadway and what's next
economic growth nagai no it is
only one of the important ingredient for
the success of that
city so that is why
it says here in the second paragraph
transportation land
well in the absence of supportive
transportation services
it will serve to limit or hinder the
potential
for a nation or region to achieve its
economic potential
thus if a society expects to develop and
grow
it must have a strong internal
transportation system
consisting of good roads rail systems as
well as
excellent linkages to the rest of the
world by
sea and air thus transportation demand
is a by-product derived from the needs
and desires of people to travel or to
transfer their goods from one place to
another it is a necessary condition for
human interaction
and economic competitiveness
so that's how it is this to transport
people and goods in order to achieve
econ economic competitiveness
okay another thing to consider or to uh
to take note is that the availability of
transportation facilities
can inst can strongly influence the
growth
and development of a region or nation
good transportation permits the
specialization of industry or
commerce reduces costs for raw materials
or manufactured goods and increases
competition between regions
thus resulting in reduced prices and
greater
choices for the consumers
management good transportation system
there is a significant
growth in the supply of goods
now with the increase of the supply of
goods then
there will be a competition for the
prices
prices
[Music]
now if you have observed during this
quarantine season
as some
roads are being blocked for the lockdown
some commodities have increased their
prices
so that happened because of the
limitation of the transportation of
goods
so as you can see there is an effect of
the having a transportation system
with the economy okay
and also other things to
think about is that transportation is
also a necessary element
of government services so aside from the
transportation of roots
there's also the services such as
delivering mail defense and
assisting territories so this is also
a way to ensure the safety of
the um community not in mama mayan
in case of an invasion or
no no not in case of innovation but any
probable uh attack so at least
preparing they can transport their their
equipments to protect the
territories now we have been mentioning
transportation
and not detours it says here
it keeps on repeating good
transportation so
meaning we need to maintain the
health of the the um transportation
facilities or
for example if the road calls
it will take time before a certain
commodity
or services can reach a certain rejoin
so
the delay of time could mean
we can loss revenue or the worst case
will be loss of lives
for example
or let's say
poorly uh built in consideration so
in the meta transfer
hospital so that's the worst case
scenario there
the loss of lives because of poor
construction of roadway or any
means of transportation okay
so that is for the importance of
transportation
now we will be tackling also
for the 1.2 the different modes of
transportation here we are to read
pages 3 to 47
of garber and hoel i have given that
already that reference
in the ms teams you can view it or
download it so that you can access it
even though you're offline
okay so let's turn to pages 34 to 47
of garber and well well uh
or marami page's name
a short introduction and
we're not going to be in depth too much
with the with the topics now we will
just tackling some
uh ideas for you to familiarize
parameters maintain the anatomy
okay so we have their modes of
transportation this is um
page 34 of uh
traffic and highway engineering by
garber and
well for edition okay
so i have uh underlined the um
specifies emphasize not in my
ideas because if we tackle everything
then
it will take hours for us to discuss
this so
i just took some um some uh
thoughts from these references okay
so we have their modes of transportation
where we have different modes of
transportation
and each mode offers a unique set
of service characteristics in terms of
travel time frequency comfort
reliability convenience and
safety so
modes of transportation because of these
characteristics
now the term level of
service is used to describe the
relative values of these attributes
now the first one that we will be
uh discussing about a smooth of
transportation is the fright and
passenger
traffic now fright and passenger traffic
from the word fright we are talking
about the transportation of
goods so anonymous
mode of transportation
to transport goods now we have their
highways
railroads water and pipelines so
i you're familiar with the highway
transportation
so you can observe my trucks nothing
perishable goods we have also the goods
used for construction you are rsv
10 reinforcing steel bars and hollow
blocks
sand gravel then you have the
railroads railroad sima train
uh you have the lrt mrt
uh the pnr okay so we actually were
talking about
the transportation of goods so we can
use
railroads for that okay water
so uh water uh we have there the roro
so you can observe in the roro
they carry goods sometimes they carry um
cars vehicles and
transporting from one region to another
or one city to
another mapalgi tanzilang
katu began so to transport them we need
vehicle or mode of transportation like
the uh barge barco
banker and the fourth one is something
that
mostly are not familiar
a mode of transportation
is pipeline so to have an idea
we have there we have google search
pipeline transportation or pipeline
trans transport
their pipeline transport is the long
distance
transportation of a liquid or gas
through a system of pipes a pipeline
typically to a market area for
consumption
you were able to observe this they are
actually transporting
[Music]
that is contained in the vessel
well um many other way path to transport
these liquids or gases that is through
pipeline that's a pilipinas and a human
pipeline transport not in
so i use the manila times
paper here so
it says there running fuel products
through a pipeline is a simple matter of
practicality and
economics pipelines are still the most
cost effective way to move a large
volume of fuels
over long distances
the possibility of accidents
and then direction
now what are the pipeline transport here
in the philippines
okay here it says the philippines has
529.5 kilometers imagine that
uh of natural gas transmission pipelines
that
transport gas from where from
the malampara gas field to fuel three
power plants
the 500 megawatts san lorenzo the one
thousand megawatt santa rita and one
thousand two hundred megawatts illian
power plants in batangas province
and uh also there are nine other natural
gas pipeline projects
that is under construction for luzon
from 2017 to 2020
and according to the government's
philippine energy plan
or pep these are the batangas
manila one or batman one the batman
ii but the uncavity or the bat cave so
batman pipeline clark
pipeline subic fort bonifacio pipeline
sukad malaya sukhot kerino lines
and a city grass distribution network
the el satov
gas pipeline so these are the
pipelines existing here in
the philippines okay
so we go back to our
discussion
we go back to our discussion okay
so that's your pipelines under the
right in passenger traffic
the next one is the public
transportation
now public transportation is a generic
term
used to describe the family of transit
services
available to urban and rural residents
so this is not a single mode but a
variety of traditional
and innovative services which should
complement each other to provide
system-wide mobility
now transit modes this included
mass transit characterized by
fixed routes publish
schedules designated networks and
specified stops
so mass transit vehicles includes
buses light rail trolleys or rapid
transit that either shares space in
mixed traffic or
operate on grid separated rights of way
so what can you think about if you say
mass transit
well i'm thinking about yuma buses
nothing
like
[Music]
a
and also what else the air airway is not
then you have the
the uh philippine airlines
another must transit what else
we have there the lrt mrt
because they have schedules or
and designated networks
okay another one is the para transit
what is a para transit it is
characterized by
flexible and personalized service
intended to
replace conventional fixed route fixed
schedule
mass transit line so hindi shafix
routing dealership fixed schedule
para transit is available to the public
on demand by
subscription or on a shared right basis
and example of this include taxi car
rental dialer ride
and specialized services for elderly
medical and other designated users
when i read this definition one thing
came to my mind
we have the grub car
grab taxi grub tricycle
so young subscriptions
just to have a ride okay
now the last one is ride sharing
it is characterized by two or more
persons traveling together
by pre-arrangement such as carpool
vanpool or shared right taxi
car pooling sharing a ride with your
friends that is
ride sharing which actually
is advisable filipinas to
reduce traffic because if you have
observed there's
so many cars there's so many vehicles in
the road
and you can observe also that
on those vehicles is
well prior to the quarantine you can
observe it already
but during this quarantine season well
you can see of course my limited number
of of
uh passengers says
sharing you share rides with people
instead of each family buying a car
and then yeah
my
if only that family shares a ride
one car or two car for that family
then in the batman to reduce the volume
of
vehicle in the road you cannot just
solve traffic
by adding roads you can actually solve
the traffic
by discipline in itself
facilities like hospitals right
but if we have discipline if each
consumer is disciplined enough
if you you um
urge
not then so that's my um
my observation so whatever your
observation is well
and that's valid then
now for the another mode we have there
the highway transportation
now highway transportation is the
dominant mode
in passenger travel and one of the
principal
fried modes bucket to say
means of transportation highways
so here in the philippines
so let's uh see the statistics
uh let's first see what
are the major expressways or highways in
the
philippines so here we have an article
list major expressways and highways in
the philippines
we have here um i'm sure
one or one or more of this is
experiencing so we have there
south lausanne expressway we have there
the s-lex
the metro manila skyway the southern
tagalog
arterial road or star tollway
the uh subi clark tarlock expressway or
sc texts
expressway or mcx
the north luzon expressways or n-lex
the manila cavity expressway or cavitex
cabitex nahiya expressway on
big depot expressway
fungus in the onion expressway or tiplex
and the most famous the edsa
or the epiphany de los santos avenue so
these are our
major expressways and highways in the
philippines
statistics okay
uh before we go to the statistics we
have there
um regarding the new
expressways being built so this article
is um uh march 2022
so what is this new philippines
expressway being built
so the article says construction is
currently underway for the new
expressway connecting laguna batangas
and
quezon provinces in the philippines and
that is
the south luzon expressway toll road or
tr4 route which will measure
67 kilometer when complete
and should reduce journey journey times
for
drivers in the area the work on the toll
road project is
split into six stretches while the
intended completion date is
on 2022 so 2022
there is a proposal for a new tall road
linking the north luzon expressway
and the manila cavity expressway it is
being
evaluated the route will measure 15
kilometer
and feature both elevated sections
and tunnels building the new road link
with cut congestion and journey times
while boosting transport to
and from manila sport so yeah they are
construction
constructing new expressway now just as
i mentioned
um
about consumer then if we reduce our
vehicle they must i think the smaller
thing in pakistan
but then if the government
has been able to see that the
construction of these two expressways
will increase
economic growth then why not no
it's just my opinion if possible
foreign
now here are the reasons why for the
road building
process here are these uh
processes
foreign
